Formula and how it works
Example with real numbers
Here is the Turnover Rate Calculator using the default values shown in the calculator above:
Inputs
| Separations | 24 |
|---|---|
| Employees at start | 150 |
| Employees at end | 146 |
| Cost to replace one employee ($) | 9,000 |
Results
| Turnover rate | 16.22% |
|---|---|
| Annual replacement cost | $216,000.00 |
| Average headcount | 148 |
With these inputs the calculator returns Turnover rate: 16.22%. Change any value in the calculator to see how the result moves.
What if you change one input?
Sensitivity check: raising Separations from 24 to 28.8 (about 20% higher) and leaving everything else as in the example above changes the results like this:
| Result | Example | After the change | Change |
|---|---|---|---|
| Turnover rate | 16.22% | 19.46% | +20% |
| Annual replacement cost | $216,000.00 | $259,200.00 | +20% |
| Average headcount | 148 | 148 | 0% |
The input that moves the result most is the one to check twice. Change it in the calculator above to test your own case.
